The invention relates to a device () of the electrochromic type comprising successively a substrate (), a reflection control coating (), a laminating interlayer (), a functional system () of the electrochromic type and a substrate (). This particular arrangement of the laminating interlayer between the reflection control coating and the functional system and the choice of the refractive index and thickness of the reflection control coating are such that the saturation values of C* in the colorimetric system (L*, a*, b*) of the device in reflection are less than or equal to 10 for angles of incidence of 60&#xb0; and 8&#xb0; relative to the normal (N) to the outer face (B) of the counter-substrate and that the absolute value of the difference between the value of C* at an angle of incidence of 8&#xb0; and the value of C* at an angle of incidence of 60&#xb0; is less than or equal to 6.
